CVS commit: src/sys/kern

[Nathan J Williams <nathanw%netbsd.org@localhost>]

Module Name:    src

Modified Files:
        src/sys/kern: kern_sig.c

Log Message:
Two fixes:

 * Change the semantics of proc_unstop() slightly, so that it is
   responsible for making all stopped LWPs runnable, instead of
   all-but-one. Return value is a LWP that can be interrupted if doing
   so is necessary to take a signal. Adjust callers of proc_stop() to
   the new, simpler semantics.

 * When a non-continue signal is delivered to a stopped process and
   there is a LWP sleeping interruptably, call setrunnable() (by way
   of the 'out:' target in psignal1) instead of calling unsleep() so
   that it becomes LSSTOP in issignal() and continuable by
   proc_unstop(). Addresses PR kern/19990 by Martin Husemann, with
   suggestions from enami tsugutomo.
